Avalanche Summary

No new reports from this region.

Snowpack Summary

Early season snowpack observations are still very limited in the region but the threshold for avalanches has been exceeded at treeline and in the alpine. Reports suggest that the snow depth at treeline is typically 110-150cm but a report from the east side of region shows only 80cm at treeline. The snowpack tapers off drastically below treeline and below around 1700m there is not yet enough snow for avalanches. On Friday and Saturday, generally light amounts of storm snow and strong winds were reported to have formed wind slabs in leeward terrain at treeline and in the alpine. Limited reports suggest the crust from the middle of November is down 50-80cm and the crust from early November is down 80-110cm.
